Theoretical Foundations of Magnetic Resonance Imaging Sequences

Abstract

We want to study Magnetic Resonance Imaging from a theoretical perspective by deriving solutions to the Bloch equations and interpreting them in an imaging context. We will cover basic transformations, analytical and numerical solutions to key sequence building blocks, the principles of Fourier imaging, and derive extended phase graphs to describe SSFP sequences.

Objective

1. Understand the basic properties of solutions to the Bloch Equations and their implications for MR sequence and system design 2. Apply learned solution techniques to obtain analytical or numerical solutions to arbitrary pulse sequences 3. Analyze and interpret theoretical solutions in the context of MR imaging.

Content

1.Basics of MRI: System Definition, Magnetization Dynamics, Signal 2.Transformation Bloch Equations (Homogenization, Rotating Frame, Complex Basis) 3. Rotation Operator Algorithm 4. RF Pulse 1: Off-Resonant Hard-Pulse 5. MR Sequences 1: Free Induction Decay and Spin Echo 6 .k-Space: Image Formation, Aliasing, Bandwidth, Point-Spread-Function 7. Steady-State Sequences: Extended Phase Graphs 8. MRI Sequences 2: Gradient-Spoiled and balanced Steady-State Free-Precession 9. RF Pulse 2: Shaped RF Pulses for Slice Selection, Hard-Pulse and Small Tip-Angle Approximation"
